I just faced with the same issue and here is what I did,
I first installed MinGw using the installation manager (with msys base included). Then I go to C:\MinGW\msys\1.0\ folder in my pc, where msys.bat (to evoke the MinGW shell) and run it. Then on that bash screen, I navigated to the folder that I wanted to install initially. After that, using “./configure” and “make” worked just fine.
